Catnip growing season:
1. The best time to plant catnip is in spring and autumn. Catnip prefers cool, full sun or partial sun environment. It is generally sown in autumn and transplanted in summer. In the south, it can be sown in spring and autumn. During this period, care should be taken to prevent root fungal infection.
2. Catnip prefers a cool environment with full sun or partial sun. It is generally sown in autumn and transplanted in summer, while in the south it can be sown in spring and autumn. The best time to harvest flowers is at the beginning of flowering. A sunny and well-ventilated location should be chosen. 
Catnip cultivation method:
1. Soil: Choose well-draining soil for planting catnip. A mixture of horticultural soil and compost is suitable. Also, the pot size should be appropriate; avoid pots that are too small, as this will hinder the growth of the catnip's roots.
2. Sowing: You can easily plant seeds directly from the purchased seeds. Spring is the recommended sowing time, with an optimal temperature of 18-22℃. Place drainage stones at the bottom of the pot, then add soil. Sow 1-3 seeds per hole, cover with about 1 cm of soil, press it down, and water appropriately. After sowing, place the pot in a cool, shady place, avoiding direct sunlight. Germination will occur in 7-10 days. After emergence, fertilize 1-2 times per week. Once the sprouts appear, increase the amount of sunlight they receive; insufficient sunlight can negatively impact their growth and flowering.
3. Care: Catnip thrives in a relatively humid environment. In summer, it needs watering almost daily, but it's also susceptible to overwatering, so water only when the soil is dry. In winter, when temperatures are lower, water sparingly. It doesn't require much fertilizer; generally, a diluted liquid fertilizer once a week is sufficient. It needs adequate sunlight daily.
4. Sterilization: Catnip is generally unaffected by pests and diseases and even has a mosquito-repellent effect. The main concern is preventing fungal infections in the roots. Avoid soils with high clay content and poor drainage, as these can lead to fungal growth and harm the plant's health. A single application of a flower-specific fungicide can effectively prevent fungal root rot. For regular maintenance, water only when the soil is completely dry.
5. Pruning: Catnip grows very vigorously, so it's important to prune it regularly. The more you prune, the more it will promote growth. Removing excessively long branches allows nutrients to be directed towards reproductive growth, encouraging the production of beautiful small flowers. Furthermore, because of its distinctive scent, it's generally not susceptible to pests or diseases as long as the pot is kept clean. However, after transplanting, watering the plant with a fungicide can reduce the risk of pests and diseases.
